The present invention is directed to im- P1OYC111G11tS in gates.

The primary object of the invention is to provide a gate so constructedthat a vehicle approaching the same will. cause the gate to open andpermit the vehicle to pass, after which the vehicle will operate meansto release the gate to permit the same to swing to its closed position.

Another object of the invention is to provide a gate so constructed thatan approaching vehicle will operate to el .val'e the gate as it swingsopen, means being provided to hold the gate open until the vehiclepasses through the gate opening, the holding means being releasable bythe vehicle to permit the gate to swing closed by gravity.

Another object of the invention is to provide a gate of this typewherein the operating mechanism is simple in construction, durable, andcan be produced at a very small cost.

li ith these and other objects in view, this invention resides in thenovel features of 35 construction, :liormation, combination andarangeiuent of parts to be hereinafter more je ly described, claimed andillustrated in the accmupanying drawings, in which Figure 1 i aperspective view showing the gate in its closed position.

covered by a platform 5, the walls of the pit being preferably formedfrom cement.

Mounted upon the platform 5 adjacent the post 1 is a collar 6 whichcoincides with the opening 7 formed in the platform, said collar havingformed interiorly thereof diametrically opposed inclined tracks 8, theupper ends of whic h terminate in vertical tracks 9,

the purpose of which will appear later. The gate 10 comprises tubularposts 11 and 12 which are connected by bars 13, the former post formingthe pivotal mounting for the gate 10.

The post 1 1 has a spindle 14 carried by its upper end for rotatablyengaging the bearin g bracket 15 mounted upon the post 1.

F ixed in the lower end of the post 11 is a plug 16 in which is mounteda transverse shaft 17 upon the ends of which are mounted rollers 18*18adapted to engage the tracks 8 and 9 of the collar 6. The plug has anaxial opening 19 in which is slidable the rod 20, said rod having itslower end extending gagement with the plate 3.

The latch rod 25 has a handle 26 thereon to permit the same to bemanually operated, there being a spring 27 engaged upon the rod fornormally urging the rod forwardly for engagement with the plate 3.

Supported between the walls 2828 of the pit 4: ar

e shafts 29 and 30, which pivotally support levers 31. and 32,respectively.

Between the walls 3333 and 3t-3-il of the pit are mounted shafts 35 and36 to which are pivotally connected the outer ends of the trip bars 37and 38, respectively. The free end of the bar 37 rests upon the lever31, while the free end of the bar 38 rests upon the lever 32 as clearlyshown F are arranged in overlapping relation, the overlapped portionsbeing located under the lower end of the rod 20 in order that when thelovers 31 and 32 are rocked in one direction the rod 20 will be movedupwardly to actuate the latch rod 25.

The levers 37 and 38 have carried thereby heads 39 and l0, which arearranged to normally extend above the plane of the platform 5, saidplatform having openings .ll 41 to permit full depression of the headswhen. encountered by a wheel of a vehicle. These heads are capable ofbeing removed when desired.

A rock shaft 42 is journaled between the walls 13 13 of the pit l andhave arms 1 1 and 15 carried by its ends, said arms having heads 16 and47 carried by their ends. This shaft provided with a lever 4-8 whichoperates between the walls 4l9-el9 of the pit. The lever 18 has itsinner end engaged with the book 50 formed upon the lower end ot the link51, said link passing through the plati'orm 5 and has its upper endpivoted to the bar 52 which is pivotally connected to the post 53. Thepost 53 is placed in longitudinal alinement with the main post 1 and isspaced therefrom a distance approximately the length of the gate 10. Thebar 52 has carried thereby a lug 5a for engagement with the free end ofthe gate when in its open position. Encircling the lin 51 and interposedbetween the bar 52 and platform 5 is a coil spring 55 which serves tonormally hold the bar in a horizontal position.

End posts 56 and 57 are employed and rotatably supported by these postsas well as by the posts 1 and 53, is a rock shaft 58, the outer ends ofwhich carry arms 59 and (30, there being an intermediate arm 61 fried tosaid shaft. The arm (31 is pivotally connected to the mljaeent end ofthe bar 52 by a link (32 in order that when the shaft is rocked the bar52 will be likewise rocked. Flexibly connected to the arms 59 and arehand rings 63 and (jet, respectively.

The posts 56 and 57 have pivotally connected thereto levers 65 and '66,respectively, said levers having flexibly connected. thercto hand rings(37 and 68. The lever (35 has pivotally connected thereto the upper endof a rod 69 which passes through the platform 5 and has its lower endconnected to the outer end of the lever 31. A red 70 is similarlyconnected to the lever (55 and has its lower end connected to the outerend of the lever 32. As shown in Figure 1 the 10 is in its closedposition. When a vehicle approaches the gate a front wheel thereof isguided upon the head 39 to depress the same, whereupon the trip bar 37will swing downwardly thus rocking the lever 31. As the lever 31 rocksthe inner end thereof will force the rod 20 upwardly, thus rocking thelever 24: to withdraw the latch rod 25 from engagement with the plate Asthe lever 31 moves upwardly it will engage the lug 21 thus forcing thepost 11 upwardly, and during this upward movement the post will rotatedue to the engagement of the rollers 18 in the track 8, thus swingingthe gate 10. As the gate continues to rotate the rollers will rise intoand upwardly in the vertical tracks 9 until the lever 31 has been rockedto its fullest extent, and the gate fully opened. It will be of courseunderstood that as the gate swings open it will also move upwardly sothat the post 12 rides upon the bar 52 for contact with the lug 54. thespring 55 will hold the bar 52 yieldably eng red with the gate tomaintain the same op .n.

The gate now being open the vehicle passes through the gate opening andis guided so that front wheel engages the head &7, which rocks the shaft42 and thus the lever 18, which pulls downwardly upon the link 51, thusrocking the bar 52, whereupon the post 12 is forced from the bar 52 bythe lug 5 1 and the gate will close by gravity. It will be of courseapparent that when a vehicle approaches the gate in an oppositedirection the head 10 will be encountered first to rock the lever 32through the means of the bar 38. hen the head 16 is depressed it rocksthe shaft 42 to release the gate to permit the same to gravitate to itsclosed position.

ln localities where snow remains a very long period, I have found itdesirable to re move the heads '39, 40, 16 and -17 and in which instancethe gate isopened and closed through the medium of the rings 63, 64:, 67and 68. To open the gate through the medium of the rings it will beobvious that when the ring 67 is pulled downwardly that the rod 69 willactuate the lever to elevate the gate and swing the same to its closedposition, the ring (38 being actuated when it is desired to open thegate from a reverse direction. Since the rings (33 and 6% control themovement of the bar 52 it will be obvious that upon operating theselevers the bar will be manipulated to permit the gate to gravitate toits closed position.

From. the foregoing, it is thought that the construction, operation andmany advantages of the herein described invention will be apparent tothose skilled. in the art, without furtherdescription, and it will beunderstood that various changes in the size, shape, and proportion andminor details of construction may be resorted to without departing fromthe spirit or sacrificing any of the advantages of the. invention.
